This web seminar took place on September 24, 2013, from 6:30 p.m. to 8:00 p.m. eastern
daylight time. The presenter was Ramon Lopez from the University of Texas at Arlington.
Jeff Nordine of the San Antonio Children’s Museum provided supporting remarks. This
was the second web seminar in a series focused on the disciplinary core ideas that
are part of the Next Generation Science Standards (NGSS). The program featured
strategies for teaching about physical science concepts that answer questions such
as “How are waves used to transfer energy and information?” and “How are instruments
that transmit and detect waves used to extend human senses?”

Dr. Lopez began the presentation by discussing the role of disciplinary core ideas
within A Framework of K-12 Science Education and NGSS. He then
shared a definition of waves and provided a refresher on electromagnetism. He also
talked about waves in relation to digital technologies. Participants had the opportunity
to ask questions and discuss ideas for classroom application with other participating
teachers.

Twenty-six states led the development of Next Generation Science Standards through
a broad collaborative process including many teachers and stakeholders. NSTA was
a partner in the standards development process. Read more about NGSS@NSTA.
